Wal mart has the best price on Motorcraft filters and syn blend Motorcraft oil.
Some come in 5 qt bottles too.
Use only Motorcraft oil filters, and you will be good to go.
I use Castrol in all my trucks, but I will stay with Motorcraft in my 07 Explorer though.
I went from 10w 30 to 5w 30 and now to 5w 20. Biggest thing I noticed is oil consumption. The 10w 30 and the 5w 20 seem to burn it up the most (maybe even more with the 5w 20), with the 5w 30 requiring little or no addition on a 5k mile oil change. You're in a cold area, so you might want to give the semi-syn 5w 20 a try. I think I'll go back to the 5w 30 at the next change.
Only problems we've had with ours has been minor things with the air ride suspension: replaced a faulty connector and put in a new pump. Oh yeah, had to put a new alternator in too. We have just 47k on ours now...
Good luck with your new ride!

By this Ford TSB below, your vehicle apparently is approved for 5W-20, which is supposed to improve mileage. I switched from 5W-30 to 5W-20 on my 5.4 and did notice an increase in mileage; and I use only the Motorcraft approved synth blend 5W-20 and an approved Ford oil filter. I gave up on using anything else back at about 40k. It runs fine on 5W-20. BTW, forget about Rislone.
